The county jurisdiction includes the island of Santa Rosa south of Pensacola; it is not part of Santa Rosa County proper. Escambia County is part of the Pensacola-Ferry Pass-Brent Metropolitan Statistical Area.
It secretes juices containing enzymes that are capable of digesting all major types of food -- carbohydrates, fats and proteins. The pancreas is the first organ to begin digesting fats. It secretes pancreatic lipase, esterase and phospholipase, which break down chemically complex fats into simple, easy-to-absorb fats. Similarly, trypsin and carboxypolypeptidase break down proteins, and pancreatic amylase breaks down carbohydrates.
Acting on a membrane phospholipid, phospholipase C cleaves off IP3, which is a small polar molecule. Remaining in the membrane is the DAG, which consists of glycerol and two fatty acids. The IP3 diffuses to the endoplasmic reticulum, which stores Ca ++ .The IP3 binds to and opens a ligand gated ion channel that allows Ca ++ to move out into the cytosol, where the Ca ++ activates various cellular processes.emaining in the membrane is the DAG, which consists of glycerol and two fatty acids.
